KeyStar

With KeyStar, you can take total command of your Android device's buttons to perform the exact actions you need.

Add up to 10 actions for each button. Not enough? Add contexts to perform a different set of actions based on the currently open app.

Still not enough? Combine KeyStar with Tasker to create your own actions and hotswap configurations on the fly based on your own rules.

Remapping works always, even with the screen and Always On Display turned off. No root needed.

Soft keys, such as home, back, and recents, are also supported. KeyStar allows you to add your own actions on top of the existing functions provided by these keys.

The engine parameters can be fine tuned to your liking. You can adjust the delays for short presses, long presses, and even customise the volume change speed when holding down the volume buttons.
